Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a scooter folding mechanism and a scooter. Background Technology

[0002] Scooters are small, portable, and a convenient and agile means of transportation and recreation. However, scooters still take up a considerable amount of space due to their height. To make scooters easier to store, many scooters are designed with a folding function. When storing a scooter, the handlebar stem can be folded up, making the scooter smaller and easier to fit into small storage spaces such as under a table or in the trunk of a vehicle.

[0003] Some scooters also feature a snap-on design on the rear wheel fender, allowing the folded handlebar stem to be attached to the fender for easy lifting. However, the fender is usually made of plastic and is a thin sheet structure, making it difficult to support the overall weight of the scooter. Under prolonged load, the fender is prone to cracking or breaking at the snap-on point.

[0004] Therefore, there is an urgent need to propose a scooter folding mechanism and a scooter to solve the above-mentioned technical problems. Utility Model Content

[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] Example 1

[0051] This embodiment provides a scooter folding mechanism. The fixed structure after folding has high mechanical strength and is not easy to break. The folded scooter is also small in size, which can meet the needs of storage in small spaces.

[0052] See Figures 1-3 The scooter includes a front wheel bracket 10 and a handlebar stem 20. The handlebar stem 20 is rotatably connected to the front wheel bracket 10 and has a use state and a storage state. Understandably, when the scooter needs to be ridden, the handlebar stem 20 is adjusted to the use state. When the scooter is not needed and needs to be stored or transported, the handlebar stem 20 can be adjusted to the storage state.

[0053] The scooter's folding mechanism includes a first connecting part 100 and a second connecting part 200. One end of the first connecting part 100 is rotatably connected to the handlebar stem 20, and the other end is provided with a first locking part 110. The second connecting part 200 is mounted on the front beam 30 connected to the front wheel bracket 10, and is provided with a first locking engagement part 210. When the handlebar stem 20 is in the retracted state, the first connecting part 100 can be rotated under external force to lock or unlock the first locking part 110 and the first locking engagement part 210.

[0054] When you need to store the scooter, first fold the handlebar stem 20 to the storage state, then rotate the first connecting part 100 on the handlebar stem 20 to lock the first locking part 110 on the first connecting part 100 with the first locking engagement part 210 on the second connecting part 200, thus completing the folding and fixing of the scooter.

[0055] When you need to use the scooter, rotate the first connecting part 100 on the handlebar stem 20 to unlock the first locking part 110 on the first connecting part 100 from the first locking engagement part 210 on the second connecting part 200, and then adjust the handlebar stem 20 from the storage state to the use state.

[0056] The scooter folding mechanism secures the scooter in its folded state through the cooperation of the first connecting part 100 and the second connecting part 200. It features a simple structure, convenient operation, and high structural stability when folded. Furthermore, the folded handlebar stem 20 can function as a carrying handle, making it easy for people to lift and move the folded scooter.

[0057] A second connecting part 200, which mates with the first connecting part 100 on the handlebar stem 20, is mounted on the front beam 30. Compared to the existing technology that uses clips to connect the handlebar stem 20 to the rear wheel fender, the front beam 30 is typically made of metal, which has higher mechanical strength than fenders made of plastic. It is unlikely to crack or break under long-term load, thus improving the long-term reliability of the second connecting part 200 and reducing the scooter's maintenance costs. Furthermore, the folding of the handlebars is not limited by the position of the rear wheel fender; that is, the handlebars can be folded further down and stored within the footrest, reducing the scooter's size when folded and minimizing its space requirements, thus meeting the needs of small-space storage.

[0058] Optionally, see Figure 2 and Figure 3 In one possible embodiment, the first locking part 110 includes a snap-fit ​​hole 111, the first locking engagement part 210 includes a latch 211, and the first connecting part 100 can be rotated under external force to engage or disengage the snap-fit ​​hole 111 with the latch 211. This configuration is simple; simply rotating the first connecting part 100 and engaging the snap-fit ​​hole 111 onto the latch 211 quickly locks the handlebar stem 20, and reversing the rotation unlocks it, making operation convenient.

[0059] When the handlebar stem 20 is in use, the first connection 100 may snag clothing or collide with obstacles during turning or bumping, affecting riding.

[0060] Further, see Figure 2 and Figure 4In one possible embodiment, the handlebar stem 20 is provided with a second locking engagement portion 120, and the first connecting portion 100 can be rotated under external force to lock or unlock the first locking portion 110 and the second locking engagement portion 120. It is understood that when the handlebar stem 20 is in use, the first connecting portion 100 can be fixed to the handlebar stem 20 by locking the first locking portion 110 and the second locking engagement portion 120, preventing the first connecting portion 100 from snagging clothing or other items during riding, thus improving the safety of riding the scooter. When the handlebar stem 20 needs to be stored, the first locking portion 110 can be unlocked for use. Furthermore, the first locking portion 110 can engage with both the first locking engagement portion 210 and the second locking engagement portion 120, reducing the manufacturing difficulty of the first connecting portion 100.

[0061] Optionally, see Figure 4 In one possible embodiment, the first locking part 110 includes a snap-fit ​​hole 111, and the second locking engagement part 120 includes an elastic snap-fit ​​protrusion 121. The first connecting part 100 can rotate under external force to engage or disengage the snap-fit ​​hole 111 and the elastic snap-fit ​​protrusion 121. When the snap-fit ​​hole 111 engages with the elastic snap-fit ​​protrusion 121, the elastic snap-fit ​​protrusion 121 can continuously press against the inner wall of the snap-fit ​​hole 111 through its own elasticity, maintaining a tight fit even on bumpy roads, resulting in good fixing effect. The elastic material of the elastic snap-fit ​​protrusion 121 has strong fatigue resistance and is not easily deformed or broken even after long-term repeated engagement, resulting in a long service life.

[0062] Furthermore, in this embodiment, the first locking part 110 includes a snap-fit ​​hole 111, the first locking engagement part 210 includes a snap-fit ​​tongue 211, and the second locking engagement part 120 includes an elastic snap-fit ​​protrusion 121.

[0063] Optionally, see [link to relevant documentation] Figure 4 In one possible embodiment, the first connecting portion 100 further includes an arc-shaped plate 130 and two connecting ears 140. The arc-shaped plate 130 can fit against the outer peripheral wall of the handlebar stem 20. A first locking portion 110 is provided at a first end in the length direction of the arc-shaped plate 130. At a second end in the length direction of the arc-shaped plate 130, two connecting ears 140 are respectively provided on both sides in the width direction of the arc-shaped plate 130. The connecting ears 140 are rotatably connected to the handlebar stem 20. When the handlebar stem 20 is in use, rotating the first connecting portion 100 causes the arc-shaped plate 130 to fit against the outer peripheral wall of the handlebar stem 20. This reduces the risk of the first connecting portion 100 snagging on clothing or colliding with obstacles while riding, and also reduces the risk of the first connecting portion 100 deforming due to external impact.

[0064] Optionally, the parameters Figure 1 , Figure 3 , Figures 5-7In one possible embodiment, the scooter folding mechanism further includes a folding assembly for switching the handlebar stem 20 between a use state and a storage state.

[0065] Specifically, the folding assembly includes a first folding member 300, a second folding member 400, and a locking structure 500. The first folding member 300 is located at the end of the handlebar stem 20 near the front wheel bracket 10, and has a third locking engagement part 310. The second folding member 400 is located at the end of the front wheel bracket 10 near the handlebar stem 20 and is rotatably connected to the first folding member 300. The first folding member 300 can rotate to close with the second folding member 400 to put the handlebar stem 20 in use, and can also rotate away from the second folding member 400 to rotate the handlebar stem 20 to a stowed state. The locking structure 500 is located on the second folding member 400 and can lock or unlock with the third locking engagement part 310.

[0066] When the handlebar stem 20 is in use, the locking structure 500 on the second folding member 400 locks with the third locking engagement part 310 on the first folding member 300, thereby restricting the rotation of the first folding member 300 and keeping the handlebar stem 20 in use. After the locking structure 500 and the third locking engagement part 310 are unlocked, the first folding member 300 can be rotated in a direction away from the second folding member 400, causing the handlebar stem 20 to rotate to the folded state.

[0067] The folding component has a simple structure, is easy to operate, and has good reliability.

[0068] Further optional, see Figure 6 and Figure 7 In one possible embodiment, the locking structure 500 includes a locking body 510 and a limiting member 530.

[0069] The locking body 510 is disposed on the second folding member 400 and is opposite to the rotation center of the first folding member 300 along the radial direction of the second folding member 400. The locking body 510 has a receiving groove 520. When the first folding member 300 is closed with the second folding member 400, the third locking engagement part 310 enters the receiving groove 520. An elongated hole is provided on one side wall of the locking body 510 near the receiving groove 520.

[0070] The limiting member 530 includes a pusher portion 531, a limiting portion 532, and a third connecting portion 533. The third connecting portion 533 passes through the elongated hole and can slide along the length of the elongated hole. The two ends of the third connecting portion 533 are detachably connected to the pusher portion 531 and the limiting portion 532, respectively, and the limiting portion 532 is located within the receiving groove 520. The limiting portion 532 is provided with a slot 5321, and the third locking engagement portion 310 includes a locking protrusion 311. When the first folding member 300 is closed with the second folding member 400, the pusher portion 531 can drive the limiting portion 532 to move under external force, so that the slot 5321 engages with the locking protrusion 311.

[0071] When it is necessary to adjust the handlebar stem 20 from the stored state to the used state, firstly, rotate the handlebar stem 20 until the first folding member 300 and the second folding member 400 are closed. At this time, the third locking engagement part 310 enters the receiving groove 520. Then, push the pusher part 531 so that the pusher part 531 drives the limiting part 532 to approach the third locking engagement part 310 through the third connecting part 533 until the slot 5321 on the limiting part 532 engages with the protrusion 311 on the third locking engagement part 310. At this time, the handlebar stem 20 cannot be rotated, thus maintaining the handlebar stem 20 in the used state.

[0072] When it is necessary to adjust the handlebar stem 20 from the use state to the storage state, first, push the pusher part 531 in the opposite direction, so that the pusher part 531 drives the limiting part 532 away from the third locking engagement part 310 through the third connecting part 533, until the slot 5321 on the limiting part 532 separates from the protrusion 311 on the third locking engagement part 310. At this time, the third locking engagement part 310 is released from restriction; then, rotate the handlebar stem 20 to the storage state.

[0073] The locking structure 500 is simple in structure and easy to operate, and it ensures good reliability in keeping the handlebar stem 20 in use. Furthermore, by providing a receiving groove 520 on the locking body 510 and storing the limiting member 530 and the third locking engagement part 310 within the receiving groove 520 for locking, the locking of the limiting member 530 and the third locking engagement part 310 is protected, reducing the risk of accidental activation and further improving the reliability of keeping the handlebar stem 20 in use.

[0074] Optionally, see Figure 7In one possible embodiment, the latching protrusion 311 has a latching surface 3111, which is engaged with the slot 5321 by abutting against a wall of the slot 5321. When the handlebar stem 20 is in use, if a force is applied to the handlebar stem 20 to rotate it away from the second folding member 400, the latching protrusion 311 will tend to rotate with the rotation center of the first folding member 300. At this time, the latching protrusion 311 will apply a force to the slot wall through the latching surface 3111. The direction of this force has an angle greater than 0° and less than 180° with the sliding direction of the limiting part 532. That is, the force will not cause the limiting part 532 to move away from the latching protrusion 311, and will thus form a reverse force on the latching protrusion 311. This reverse force cancels out the force applied by the latching protrusion 311, making the latching protrusion 311 unable to rotate, and ultimately allowing the handlebar stem 20 to be reliably maintained in use.

[0075] Optionally, see Figure 6 In one possible embodiment, the pusher portion 531 is located on the outer wall surface of the receiving groove 520, and the pusher portion 531 is provided with a protrusion 5311. The protrusion 5311 has a raised center and two concave arc surfaces on both sides. The operator can push the pusher portion 531 by using different concave arc surfaces, enabling the pusher portion 531 to move in different directions. By providing the protrusion 5311, the difficulty for the operator to push the pusher portion 531 is reduced, and the convenience of operation is improved.

[0076] Further optional, see Figure 5 The push handle 531 is equipped with an anti-slip layer. By setting the anti-slip layer, the frictional resistance between the operator's hand and the push handle 531 is increased, making it easier for the operator to apply force and optimizing the operating experience.

[0077] Further, optionally, see also Figure 5 The push handle 531 is provided with an indicator mark. For example, in this embodiment, one end of the push handle 531 is provided with an indicator arrow and the indicator text "OPEN" to prompt the operator on the direction of unlocking the card protrusion 311. The opposite direction of the indicator arrow is the direction of locking the card protrusion 311. The structure is simple and easy for the operator to understand.

[0078] Optionally, see Figure 6 and Figure 8 In one possible embodiment, one end of the locking body 510 is rotatably connected to the second folding member 400 along its length, and the other end is rotatably connected to a connecting rod 540. The other end of the connecting rod 540 is rotatably connected to the first folding member 300. When the first folding member 300 and the second folding member 400 are in the closed state, the connecting rod 540 is stored in the receiving groove 520.

[0079] Specifically, the rotatable connection between the locking body 510 and the connecting rod 540 is located within the receiving groove 520. When the first folding member 300 and the second folding member 400 are in the closed state, the rotatable connection between the connecting rod 540 and the first folding member 300 is also located within the receiving groove 520, allowing the connecting rod 540 to be completely stored within the receiving groove 520. This arrangement forms a four-bar linkage 540 mechanism with the first folding member 300, the second folding member 400, the locking body 510, and the connecting rod 540, making the force on the rotatable connection more even and improving the folding stability of the scooter folding mechanism. Simultaneously, the locking body 510 is relatively small, allowing the connecting rod 540 to be stored within the receiving groove 520, resulting in a more compact structure.

[0080] By setting the linkage 540, the rotation angle of the handlebar stem 20 can be limited, which improves the reliability of the handlebar stem 20 in the retracted state.

[0081] Furthermore, when the first folding member 300 and the second folding member 400 are in the closed state, the length direction of both the locking body 510 and the connecting rod 540 housed in the receiving groove 520 is consistent with the length direction of the handlebar stem 20. At this time, the connecting rod 540 can press against the first folding member 300, which restricts the rotation of the first folding member 300 to a certain extent.

[0082] Optionally, see Figure 4 , Figures 6-8 In one possible embodiment, the first folding member 300 is provided with a first rotating connecting portion 320, and the second folding member 400 is provided with a second rotating connecting portion 410. The second rotating connecting portion 410 is rotatably connected to the first rotating connecting portion 320. The second rotating connecting portion 410 is provided with a limiting boss 411. When the handlebar stem 20 is in the retracted state, the first folding member 300 abuts against the limiting boss 411. Through the cooperation between the limiting boss 411 and the first folding member 300, the handlebar stem 20 can be restricted from continuing to rotate towards the vehicle body, thereby effectively avoiding hard collisions or frictional impacts between the handlebar stem 20 and the vehicle body structure, ensuring the structural reliability of the vehicle body and the handlebar stem 20.

[0083] To facilitate understanding, we will now combine Figures 1-8 Here is a brief introduction to how to use this scooter's folding mechanism:

[0084] See Figure 1 and Figure 2 In its initial state, the handlebar stem 20 is in use.

[0085] First, the operator pushes the pusher 531 according to the indicator on the pusher 531 to separate the latch 311 from the slot 5321 and unlock the first folding piece 300.

[0086] Then, see Figure 1 As shown by the arrow, the operator uses one hand to rotate and lock the main body 510, and the other hand to hold the handlebar stem 20 to rotate the handlebar from the use state to the storage state.

[0087] Finally, see Figure 3 As shown by the arrow, the operator unlocks the first connecting part 100 on the handlebar stem 20 from the second locking engagement part 120, and rotates the first connecting part 100 to lock the first locking part 110 on the first connecting part 100 with the first locking engagement part 210 on the second connecting part 200, thus completing the folding and fixing of the scooter.

[0088] The folding mechanism of this scooter is simple in structure and easy to operate, and the scooter has high structural stability when folded. Furthermore, the folded handlebar stem 20 can also serve as a handle, making it easy for people to lift and move the folded scooter.
